Abstract

A RSA encryption scheme includes a modulus in which at least one set of bits is of a predetermined configuration. The configuration may be selected to replicate the identity of the recipient or other information normally transmitted between the parties or may be information stored by the sender to allow only the balance of the modulus to be transmitted with the sender subsequently reconstructing the modulus.
